PENNSYLVANIA, ASSIGNOR T0 ALUMINUM GOM- PANY OF AMERICA, '01?IPITTSBURGH, PENNSYLVANIA, A CORPORATION 8F PENN- SYLVANIA MEANS FORFASTENING CORRUGATED SHEETS AND THE LIKE Application filed August 2,1929. Serial No. 383,110.

' This invention relates to means for fastening or connecting corrugatedor flat roofing sheets or siding sheets to structural elements, such asbeams, purlins, girders and the like.

Prior to this invention, sheet metal roofin and siding sheets, eitherplain or corrugate were connected or attached to structural elements,such as purlins, rafters, beams, girders by means of two common types offastening devices. One type consisted of a pair of headed memberspassing through the material to be fastened and'around the structuralelement to which it was to be secured, the free ends thereof beingtwisted together preferably beneath the lower flange of the purlin. Inthe other type of fastener, two headed members were also used. One ofthe headed members however, was provided with a bight at any desiredpoint whereby, after the ends of the two members were twisted togetheras above mentioned, an looseness could be taken up by twisting the b1ght. Both of these types, by reason of the two headed members, made itnecessary to form two holes in the material to be secured. Also, due tothe fact. that two headed members were used, a uniform tension in bothmembers could not be obtained and there frequently resulted anundesirable looseness.

I have found that with a fastenin device comprising a headed memberastened through a single hole in the material to be secured andcooperating with a flexible pliable material adapted to be securedto'the structural element, I can provide a fastening device which inaddition to being simple and easy to apply and remove eliminates onehole secured and is substantially free from any looseness.

It is therefore an object of this invention to provide means forfastenin corrugated sheets or sidings to structural e ements comprisinga single means passing through said sheets and means cooperatingtherewith to fasten said first named means to said structural element.

. Another object of this invention is to provide a device for fasteninga sheet of material to a structural element comprising a headed memberpassing through said sheet cured in such a manner that it will passaround the structural element.

Other objects of this invention will appear from the followingdescription, appended claim and accompanying drawings in which:

Figure 1 illustrates the fastening device constituting this invention,the sheet and structural element bein shown in section.

F1 ure 2 is an end view of Figure 1.

Re errmg to the drawings in which like reference numerals designate likeparts, the reference numeral 1 designates corrugated sheets adapted toform a roofing or siding, disposed on purlins 2 or other structuralelements. A headed member 3 extends through a hole 4 formed in thecorrugated material. Theshank of the member 3 is provided with a hole 5through which a flexible pliable member 6 is adapted to pass. The ends 7of the member 6 are brought together and twisted beneath the lowerflange of the purlin 2, as indicated at 8, forming a strap embracing theurlin and securing the headed member to t e corrugated sheet. By reasonof this construction, the flexible member ad- ]usts itself during thetwisting of the ends thereof so that a secure fastening, substantiallydevoid of any looseness, is obtained.

The flexible member 6 may be a wire formed of a solid piece of suitablematerial, such as annealed iron, soft drawn copper or aluminum, of sucha character that it will resist considerable strain and will permit theends thereof to be readily twisted together.

The ends 7 of the member 6 are indicated in the drawings as beingbrought together beneath the lower flange of the purlin. It

is to be understood that the ends 7 of the 2 Lasagna purlin asillustrated. In practice it is usual to dispose a gasket 9 between thehead 10 I of the headed member 3 and the corrugated sheet 1. 5 Theheaded member 3 may be a rivet bolt, pin orthe like. The head thereofmay be formed of any suitable design. It. may have a curved top and aflat bottom or it may be made so as to conform to the shape of the 10corrugated material.

The fastening means above described 1s simple and efiicient. It is easyto apply and remove, if desired. The fastener is-capable of givin adirect pull on the sheet to be secured. ue to the structure and locationof the cooperating arts, a fastener substantially' free from ooseness isobtained.

I claim: 7 e A device for fastening a sheet of material 00 to astructural element comprising a'headed member passing through said sheetand having a hole in the shank thereof, a wire passing through said holeand around said structural element, said wire having its ends twistedtogether whereby a strap is formed, said headed member being so disposedas to form the least number of bends in said wire. a In testimonywhereof, I have aflixed my signature to this s ecification.
